- Added blank lines for better separation of test cases in multiple test files. - Reformatted event handling in tests for clarity and consistency. - Ensured consistent use of multi-line formatting for dictionary arguments in event handling. - Improved assertions and test descriptions for better understanding. - Updated test cases across various modules including test_stream_state, test_stream_utils, test_summarization, test_thread_selector, test_tool_error_handler, test_tui_widgets, test_ui_runtime, and test_wechat_channel.
